I am new to Lyx, and using version 2.0.6, and Mac OS 10.9.1

When I click on the EYES BUTTON on a little one page example file for
xetexCV, it takes 1 minute 57 seconds for lyx to come up with anything, and
that 'anything' is an error message saying File does not exist:
/var/folders/zh/
5qprckdd5bg4xn5ddpqy7np8gn/T/
lyx_tmpdir.L10103/lyx_tmpbuf7/example4-xetex4-LyX.dvi


So it does seem slow. If I install the new beta version, will I loose the
changes I made to the lyx I already installed? For example I put some things
inside one of the folders within the app itself while trying to get this
xetexCV document class working (still getting help on that in another thread).

Thanks.

Yes, you'll loose your changes.

You should rename your LyX 2.0.6 application folder before if you want to 
preserve it.

But, as far as I understood the solution to your problem (in the other thread) 
you
should have made the modifications inside the library folder of your home 
directory.

Re: LyX very slow on Mac

Hi Jerry,

I just tested again. On my computer there IS
a considerable speed up in 2.1. In 2.0.6 I do the two
finger scroll and then wait and wait. In 2.1 the
scroll is quite fluent. Not as fast as, for example,
MS Word, but acceptable.

But then, it could be a different problem. In
my case it was not only the scroll that got slower.
Everything in LyX was slow, for example insert
math. That seems to have been solved with 2.1.

Whoa, hold on here. I can't let this thread end here. The long-standing 
classic scrolling problem on OS X remains with 2.1.0beta2.

Anders seems to have had some sort of other problem where LyX 2.0.6 was getting 
progressively slower over time and was specific to his machine.

The scrolling problem is NOT fixed in 2.1.0beta2 and remains as it has in other 
versions. As has been discussed in detail in the past on this list in various 
threads, setting
  \force_paint_single_char 0
in the LyX preferences more than doubles the scrolling speed over setting it to 
1. With it set to 0, scrolling behavior is marginally acceptable, where by 
scrolling I mean clicking in the elevator bar and advancing the display one 
page at at time as fast as possible, or by using the two-finger swipe to either 
scroll a little bit at a time or with the ballistic swipe to 
two-finger-scroll over a larger area. (OS X no longer uses arrows at the ends 
of its elevator bar). I say marginally because at 0, scrolling does not make 
me want to kill myself but still lacks the massless feel that a native Mac 
program displays while scrolling. And of course, with the setting at 0, text 
spacing is incorrect and for example it is not possible to discern if there is 
a space between some words without placing the cursor there and using the arrow 
keys to see if it moves when an arrow key is pressed.

Here are some scrolling times in seconds for the LyX User Guide versus LyX 
version and the value of force_paint_single_char in the corresponding 
preference file. I am using OS X 10.8.5. I did not check if the User Guides are 
significantly longer for 2.1 versus 2.0.6. However, the length of the document 
does not affect scrolling speed in general. It is important to note that 
scrolling speeds up briefly when little text is displayed such as for graphics 
or sparsely populated tables. And most important, these times do not adequately 
convey the much different user experiences between 0 and 1 settings--it is like 
the difference between running on a track and running in deep mud, plus latency.

LyX 2.1.0beta2 \force_paint_single_char 0  10
LyX 2.1.0beta2 \force_paint_single_char 1  23

LyX 2.0.6  \force_paint_single_char 0  11
LyX 2.0.6  \force_paint_single_char 1  22

Within measurement error, these times are essentially identical.

My understanding from a not-too-distant post on the list is that there is a 
patch but is incomplete and has not been applied to 2.1.0beta2.
